Ａもの大ｋｌ ＩＡＥを流す必要がある。このように、
一つのコイルに１ｏＡ程度の大電流を流したい場合がし
ばしば起こる。Most of the recent switching sources have an output of about 50 to 100W.
Many of them are mainly used for driving (transistors, logic). This TTL drive is mainly a type that applies +5V's Narita, and this coil has a voltage of 10 to 20V.
A big kl IAE needs to be played. in this way,
It often happens that a large current of about 1oA is desired to flow through one coil.

引き出している。FIG. 1 shows a perspective view of an example of a conventional printed coil. In this printed coil 1, a conductor 2 is wound three times in a thinly wound manner, and a conductor 2 is drawn out through a through hole 6 to the opposite side of the substrate.

コイルを通常のプリントコイルで作製する為には、導体
中を広く取るか、又は導体厚を厚くする必要があった。When the conductor 2 is made of copper metal, the current density is usually limited to about 6 to 6 A/lad in order to keep the temperature rise of the coil within an appropriate range. Due to this limitation, in order to manufacture a transformer coil that can tolerate large currents using a normal printed coil, it is necessary to make the conductor wider or to increase the thickness of the conductor.

。However, regarding the inside of the conductor, there is a limit red foot due to the dimensions of the transformer winding frame, and if it is made wider than this limit, the overall size of the transformer will increase.Also, regarding the conductor thickness, copper clad plate is used. When forming a coil by etching, it is difficult to form a thick film due to the problem of etching type, and it is also difficult to form a coil by methods such as printing, plating, and vapor deposition. As described above, the conventional printed coil manufacturing technology is disadvantageous for large-volume coils.
本発明は上記の欠点を解決し、大容端覗流に耐え得るプ
リントコイルを提供することを目的とする。It is an object of the present invention to solve the above-mentioned drawbacks and provide a printed coil that can withstand large end peeking currents.

る。For example, the present invention can be applied to a printed coil formed by etching a copper clad plate, or printed on an insulating board or insulating film. A metal plate or metal foil formed into a coil shape using a punching knife or the like is bonded to a glue coil formed by deplating, vapor deposition, etc. to increase the tolerance and make a print that can withstand large currents. This is how you get the coil.
